Thermal Grease, Paste, and Pads – Know the Difference

The fact that thermal paste come in a wide variety of names is likely the reason why many people see thermal grease and thermal paste as two different types of thermal interface materials.

The names, however, are not solely limited to grease and paste.They are also referred to as heat paste, thermal goop, thermal gel, heat sink compound, thermal compound, thermal interface material, CPU grease, and the list just goes on.

So you may be wondering:

What’s with all the debate about thermal grease vs paste, then?

They both are the same, it’s just that thermal grease/paste come in different brands and types, which varies in both composition and effectiveness altogether. Our best thermal paste review  offers a better explanation of how 5 brands differ in performance

Types of Thermal Paste

There is no difference between thermal grease and thermal paste. However, there are 3 types of thermal interface material or TIM you could find in the market – these are the metal based TIMs, the ceramic based TIMs, and the silicon based TIMs.

Below is a list of their pros and cons.

Now that you know what really makes each TIM different from each other, we’re going to look at our personal picks.

Best Metal-Based TIM

Best Ceramic-Based TIM

Silicon-Based TIMs, as defined in the table, are TIMs that usually come on stock. Not the best performing TIMs but should do the job pretty well as long as regular usage is concerned. Having to resort to either of our top picks will be recommended for overclocking purposes.

Below is a graph showing temperature readings in idle state and in a load state. You could see that temperature output varies not only on the type of TIM but also varies from brand to brand.

Other Types of Thermal Interface Materials vs Thermal Paste

Thermal Pads vs Thermal Paste

You could also find thermal pads in the market. Although they are easy to install, the fact that they don’t perform well in conducting heat is what makes thermal paste superior. In most cases, you could find them in stock or prebuilt computers.

Thermal Tapes vs Thermal Paste

You may have stumbled upon the name. Thermal tapes are not the same as thermal pastes and greases. Using these types of thermal adhesives leave your chipset and your heatsink to stick together.

Use this only and only when you know what you are doing. Perhaps the circuit does not have mounting pins or a lock mechanism. For this matter, it is a great time to consider using thermal tapes to keep the heatsink and the circuit together.

Conclusion

Thermal grease, thermal paste, thermal grunk, heat sink compound, thermal compound – they all are the same. It all boils down to choosing the best one that makes a huge difference in keeping temperatures low.

Depending on the need, a thermal paste may come in handy over thermal paste. Make sure you look at what perfectly suits your needs before making any purchase.
